EN 61747-2020 is a technical standard that specifies the requirements and test methods for liquid crystal display (LCD) modules. It was developed by the European Committee for Electrotechnical Standardization (CENELEC) and is widely recognized in the industry as a benchmark for quality and performance of LCD modules.
The Purpose of EN 61747-2020
The main purpose of EN 61747-2020 is to provide manufacturers, suppliers, and customers with a clear set of guidelines and criteria to ensure the reliable and consistent operation of LCD modules. By adhering to this standard, companies can enhance the quality and durability of their products, which ultimately benefits end-users.
Key Requirements of EN 61747-2020
EN 61747-2020 outlines various requirements that LCD modules must meet to comply with the standard. These include electrical and mechanical characteristics, optical performance, environmental conditions, and reliability testing. Let's take a closer look at some of these key requirements:
Electrical Characteristics: This section covers parameters such as input voltage, power consumption, signal interface, and response time. Compliance with these specifications ensures that the LCD module operates efficiently and reliably under different electrical conditions.
Mechanical Characteristics: Here, EN 61747-2020 defines requirements related to module size, thickness, weight, and mounting methods. These criteria aim to ensure proper integration of LCD modules into different applications while considering physical constraints.
Optical Performance: The standard sets forth specifications for brightness, contrast ratio, viewing angle, color gamut, and other visual attributes. These requirements define the expected visual quality and performance of LCD modules in terms of image clarity and color reproduction.
Environmental Conditions: This section addresses the operating temperature range, humidity, and other environmental factors that LCD modules should withstand without degradation in performance or reliability. It helps ensure the modules can function optimally even under challenging conditions.
Reliability Testing: EN 61747-2020 includes a comprehensive set of tests to assess the durability and long-term performance of LCD modules. These tests simulate various real-life scenarios, such as vibration, thermal shock, and lifecycle testing, to validate the module's robustness and reliability.
In Conclusion
EN 61747-2020 serves as an essential standard in the LCD industry, providing a common framework for manufacturers to ensure the quality and performance of their products. By complying with its requirements, companies can enhance customer satisfaction and confidence in the reliability of LCD modules. Moreover, end-users can expect consistent performance and longevity from devices incorporating EN 61747-2020 compliant LCD modules.
